However, this does not influence our evaluations. Our opinions are our own. Here is a list of our partners and here's how we make money.

For small businesses that want to accept credit cards, finding a processor is the first step. The best credit card processing company depends on which features are most important to your business. NerdWallet looked at factors such as:

Processing costs.
Speed of setup.
Flexibility to accept payments in-person, online or both.
How quickly you receive funds.
Strength of customer support.

Here are our top picks.

More about these products

NerdWallet’s top credit card processing companies below fall into two major categories:

Merchant account providers: With providers that offer merchant accounts, which are special bank accounts that hold funds from card payments, you have to go through an approval process to open an account and start accepting credit card payments. These accounts are generally more scalable and competitively priced than accounts offered by payment service providers.
Payment service providers: Payment service providers aggregate transactions from multiple companies in a merchant account. Setup is significantly faster than with a merchant account provider. While the upfront vetting process is less rigorous, businesses can face more ongoing scrutiny over transactions than they would with a merchant account. This can result in more frequent account freezes if the provider perceives that a business is not complying with the terms of service.

They also follow one of two pricing models:

Interchange-plus pricing: Transaction fees include the interchange rate, which is set by the card networks (such as Visa or Mastercard) and varies based on the type of card used and your business type, plus a markup determined by the processor.
Flat-rate pricing: Transaction fees are the same flat rate for all payments accepted a certain way; for instance, the same rate would apply to all in-person card payments and a different rate could apply to all online transactions.

In general, a merchant account with interchange-plus pricing is more cost-effective for businesses with high sales volumes. Businesses with lower sales volumes are generally better off with a PSP because of the easy setup and straightforward pricing.

Best overall: Helcim

Type: Merchant account provider. Price: Volume-dependent. For merchants processing in-person retail payments with monthly sales of $25,000 or less, cost includes interchange rate plus Helcim’s markup of 0.3% plus 8 cents per transaction. For example, a business paying this rate would pay a total of 1.8% plus 8 cents if the interchange rate was 1.5%.

Helcim's pricing model is transparent, with no hidden fees. The company has well-rated customer support as well as comprehensive support resources on its site. You receive automatic volume discounts as your business grows and transactions increase. Helcim uses interchange-plus pricing with volume-based discounts, making it a particularly cost-effective option for businesses with high monthly sales.

Best all-in-one option: Square

Type: Payment service provider. Price: For in-person payments, standard processing fee is 2.6% plus 10 cents per transaction.

Square stands apart from the competition with its flat-rate pricing and end-to-end payment processing solution. This means it handles most aspects of a credit card transaction, so you don’t need to purchase a payment gateway (a payment processing portal) or point-of-sale system from separate providers.

Best for membership-style pricing: Stax (formerly Fattmerchant)

Type: Merchant account provider. Price: Monthly subscriptions start at $99. For in-person transactions, processing fee is 8 cents per transaction plus interchange fee; for keyed-in transactions, it’s 15 cents per transaction plus interchange fee.

Stax's membership pricing model can easily save businesses enough money to justify the monthly fee, especially if they have high sales volumes. Same-day funding for an additional fee and in-house 24/7 customer support also make Stax a solid choice.

Best for e-commerce businesses: Stripe

Type: Payment service provider. Price: 2.9% plus 30 cents per transaction.

Stripe enables your business to accept a wide range of online payment methods, including mobile wallets like Alipay, Apple Pay and Google Pay. Stripe also lets you offer financing options to customers through buy-now-pay-later companies like Klarna and Afterpay.

Best for high-volume sales: Payment Depot

Type: Merchant account provider. Price: Plans start at $79 per month (for up to $50,000 a month in processing). Processing fee is 15 cents per transaction plus interchange rate for the Starter plan.

Payment Depot's rates make it a cost-efficient option, especially for businesses that can qualify for the lowest rates by processing $300,000 or more per month. Payment Depot's lowest-tier plan has a cheaper monthly fee than Stax, and its customer support is well-rated on most review websites.

Best for high-risk businesses: PaymentCloud

Type: Merchant account provider. Price: Quote-based.

PaymentCloud works with businesses in high-risk industries, including those selling age-restricted products like tobacco and firearms, businesses, such as electronics resellers, that have high chargeback rates, or those that may face a higher risk of fraud, such as finance companies. PaymentCloud also provides round-the-clock customer support for businesses in these industries. Pricing depends on the level of risk involved in your business.
